  • Low Energy Ne Scattering from Metal Surfaces using MARISS (.pdf)
    . Assuming that P+ is a function of the reciprocal (inverse). velocities, it has become a custom to plot the natural. logarithm of the normalized intensity lnS versus 1/v by using. the following experimental approaches: · variation of the scattering angle at fixed primary energy or. variation
  • Laser Diffraction
    to calculate particle size distributions if the intensity of light scattered from a sample are measured as a function of angle. This angular information needs to be compared with a scattering model (Mie theory) in order to calculate the size distribution. The technique has a very large dynamic range
  • Particle Characterization Technologies
    intensity of scattered light as a function of sample concentration. The intensity of scattered light that a macromolecule produces is proportional to the product of the weight-average molecular weight and the concentration of the macromolecule. For small molecules, which show isotropic scattering

    that certain proteins might adhere to the stationary phase during elution, yielding erroneous molecular weight determinations. A better approach is to equip the SEC/GPCsystem with a light scattering detector, enabling accurate molecular weight determinations without the need for column calibration
